Light sensor (0.1..10 W/m²)

The Light sensor 0513 uses a photodiode Optrex p.n. OP555C to measure light intensity. The sensor's range is from 0.1 W/m2 to 10 W/m2. For comparison: the light intensity on a cloudy day is approximately 8 W/m2. The sensor is direction dependent and achieves a maximum output when the end of the probe is pointed directly at the light source. The sensor is sensitive in the visible and near-infrared (IR) light range. This means that the sensor can be used for measurements of IR emitting diodes as well as visible light sources. The sensor is designed to work in air only; it is not waterproof.

The Light sensor can be used for measurements of changes in the light intensity:• Darkening of a solution caused by a chemical reaction.• The rapid changes of the light intensity for example of a computer screen.• Effects caused by on/off switching.• Light interference.

The Light sensor has a built-in resistor for automatic sensor identification and can be directly connected to analog BT inputs of the CMA interfaces.

Technical specifications of the sensor are described in its User's guide.
